Description

Technical Field

[0002] Water-cooled central air conditioning refers to cooling water through cooling water towers and cooling water pumps, so that the refrigerant in the condenser of the water-cooled unit is cooled. The cooled refrigerant flows into the evaporator, cools the circulating water through the evaporator, and the cooled water is sent to the indoor terminal equipment (fan coil unit) to exchange heat with the indoor air to achieve temperature regulation.

[0003] According to a Chinese patent with authorized publication number CN219775958U, an energy-saving device for a central air-conditioning chilled water circulation device is disclosed. The high-temperature wastewater generated by the central air-conditioning contacts a plurality of blades, thereby driving the connecting shaft to rotate, thereby driving the driving bevel gear to rotate, and driving the four driven bevel gears meshing with it to rotate, thereby driving the rotating shaft to rotate. A plurality of stirring blades are fixedly connected to the outside of the rotating shaft. When the rotating shaft rotates, the plurality of stirring blades are driven to stir the inside of the high-temperature wastewater, thereby accelerating the dissipation of heat from the high-temperature wastewater.

[0004] In actual use of the above scheme, the driving bevel gear and the driven bevel gear work in a high temperature and high humidity environment. The high temperature environment will cause oxidation on the gear surface, thereby reducing the hardness and accelerating the wear of the gear tooth surface. The humid environment will cause rust on the gear surface, which may result in failure to achieve the expected energy-saving effect, shorten the service life of the gear, and reduce the practicality of the energy-saving device of the existing central air-conditioning chilled water circulation device.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0031] See also Figure 1-3 , the utility model provides a technical solution: an energy-saving device for a central air-conditioning chilled water circulation device, comprising a cooling tower body 1, a water inlet pipe 3 fixed to the top of the cooling tower body 1, and a heat dissipation energy-saving structure 200 installed inside the cooling tower body 1 for achieving energy-saving purposes;

[0032] Through the coordinated use of the cooling tower body 1, the water inlet pipe 3 and the heat dissipation and energy-saving structure 200, it can effectively avoid the situation in a high temperature and high humidity environment where the gear surface is oxidized or rusted, resulting in the failure to achieve the expected heat dissipation effect for the high-temperature wastewater generated by the central air-conditioning. It ensures that the high-temperature wastewater generated by the central air-conditioning can be dissipated to the expected effect, thereby achieving the purpose of energy saving and improving the practicality of the energy-saving device of the central air-conditioning chilled water circulation device.

[0033] In this embodiment, the heat dissipation and energy-saving structure 200 is a structure for achieving energy saving.

[0034] like Figure 1 and Figure 2 As shown, the heat dissipation and energy-saving structure 200 includes a diversion component 201 installed inside the cooling tower body 1 for diverting high-temperature wastewater, and a heat dissipation component 202 installed inside the cooling tower body 1 for allowing the high-temperature wastewater to discharge more heat.

[0035] It should be noted that a plurality of heat dissipation holes 2 are provided on the top of the cooling tower body 1 to discharge heat, and two fixing seats 4 are fixed on the bottom of the cooling tower body 1 to make the cooling tower body 1 more stably fixed.

[0036] In this embodiment, the diversion component 201 is a structure for diverting high-temperature wastewater.

[0037] like Figure 1 As shown, the diversion assembly 201 includes a mounting plate 2011 fixed inside the cooling tower body 1, a triangular block 2012 fixed to the top of the mounting plate 2011, and two fixing rods 2013 respectively fixed to the left and right sides of the mounting plate 2011; the triangular block 2012 is used to divert high-temperature wastewater.

[0038] It should be noted that the opposite ends of the two fixing rods 2013 are respectively fixed to the inner left wall and the inner right wall of the cooling tower body 1, and the fixing rods 2013 make the installation of the mounting plate 2011 more stable.

[0039] In addition, the length and width of the triangular block 2012 are respectively greater than the diameter of the water inlet pipe 3, ensuring that the triangular block 2012 can divert and process the high-temperature wastewater.

[0040] In this embodiment, the heat dissipation component 202 is a structure that enables high-temperature wastewater to discharge more heat.

[0041] like Figure 1 and Figure 3As shown, the heat dissipation component 202 includes two inclined plates 2021 respectively fixed to the left and right inner walls of the cooling tower body 1, six triangular plates 2022 respectively fixed to the tops of the two inclined plates 2021, a rock wool board 2023 fixed to the bottom of the inclined plates 2021, a non-woven fabric layer 2025 fixed to the left inner wall of the cooling tower body 1, and a partition 2026 fixed to the inside of the cooling tower body 1; the non-woven fabric layer 2025 prevents high-temperature waste water from splashing out of the cooling tower body 1.

[0042] It should be noted that a through hole 2024 is provided on the left side wall of the cooling tower body 1, and the non-woven fabric layer 2025 is fixed inside the through hole 2024 to effectively discharge the heat in the cooling tower body 1. The non-woven fabric has water-repellent and breathable properties, can effectively discharge the heat inside the cooling tower body 1, has a certain waterproof function, can prevent general liquid splashing, and can effectively prevent splashing water from splashing from the through hole 2024 to the outside of the cooling tower body 1.

[0043] In addition, a drainage hole 2028 is opened at the top of the partition 2026, and a flow groove 2027 is opened at the top of the partition 2026. The right side of the flow groove 2027 is connected to the drainage hole 2028 to ensure that high-temperature wastewater can enter the bottom of the cooling tower body 1 through the flow groove 2027 and the drainage hole 2028.

[0044] In addition, the front and back sides of the triangular plate 2022 are respectively fixed to the inner front side wall and the inner rear side wall of the cooling tower body 1 to ensure that the flow rate of the high-temperature wastewater can be slowed down. The rock wool board 2023 has good waterproofness and heat absorption, and can effectively absorb the heat dissipated by the high-temperature wastewater. After the high-temperature wastewater flows out, the heat will be discharged automatically.

[0045] The working principle of the above embodiment is:

[0046] When in use, the high-temperature waste water generated by the central air conditioner is discharged into the cooling tower body 1 through the water inlet pipe 3, and then the high-temperature waste water first contacts with the triangular block 2012, and the high-temperature waste water is diverted by the triangular block 2012. The high-temperature waste water on the right side directly falls to the surface of the bottom inclined plate 2021. The flow rate of the high-temperature waste water is slowed down by setting the triangular plate 2022, and then the high-temperature waste water enters the inner bottom of the cooling tower body 1 through the flow groove 2027 and the drainage hole 2028, which effectively prolongs the contact time between the high-temperature waste water and the air, so that the high-temperature waste water can release more heat, while the high-temperature waste water on the left side falls. On the surface of the top inclined plate 2021, it first passes through the top inclined plate 2021 and then enters the bottom inclined plate 2021, thereby reducing the volume of the high-temperature wastewater passing through at one time, thereby effectively increasing the contact area between the high-temperature wastewater and the air, so that the high-temperature wastewater can release more heat. At the same time, the heat dissipated by the high-temperature wastewater can be effectively discharged to the outside of the cooling tower body 1 through the heat dissipation holes 2 and the through holes 2024, and the heat can also be absorbed by the rock wool board 2023. Then, when the high-temperature wastewater is cooled by the cooling filler at the bottom of the cooling tower body 1, the energy consumption can be effectively reduced, thereby achieving the purpose of energy saving.

[0047] Compared with the prior art, the energy-saving device of the central air-conditioning chilled water circulation device, through the coordinated use of the cooling tower body 1, the water inlet pipe 3 and the heat dissipation energy-saving structure 200, can effectively avoid the situation in a high temperature and high humidity environment where the gear surface is oxidized or rusted, resulting in the failure to achieve the expected heat dissipation effect on the high-temperature wastewater generated by the central air-conditioning, thereby ensuring that the high-temperature wastewater generated by the central air-conditioning can be dissipated with the expected effect, thereby achieving the purpose of energy saving, improving the practicability of the energy-saving device of the central air-conditioning chilled water circulation device, and solving the problem of low practicability of the energy-saving device of the existing central air-conditioning chilled water circulation device.

[0048] The electrical components mentioned in the text are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the text.
